In a web application the role of session management is very
critical. Most of the languages available today do not really support different
modes of session management. They used to follow the traditional way of
maintaining the session that is through web servers.
But in .NET applications we have multiple options to opt for
the session mode. The different session management modes available in .NET
technology are InProc, SQLServer and State Server. Among them, InProc is the
default method that keeps the session in Web servers (IIS).
